Class toString() method in Java with Examples

The toString() method of java.lang.Class class is used to convert the instance of this Class to a string representation. This method returns the formed string representation.

Syntax:

public String toString()

Parameter: This method does not accept any parameter.

Return Value: This method returns the String representation of this object.

Below programs demonstrate the toString() method.

Example 1:

// Java program to demonstrate toString() method

public class Test {
    public static void main(String[] args)
        throws ClassNotFoundException
    {
        // returns the Class object for the class
        // with the specified name
        Class c1 = Class.forName("java.lang.String");

        System.out.print("Class represented by c1: ");

        // toString method on c1
        System.out.println(c1.toString());
    }
}

Output:

Class represented by c1: class java.lang.String

Example 2:

// Java program to demonstrate toString() method

public class Test {
    public static void main(String[] args)
        throws ClassNotFoundException
    {
        // returns the Class object for the class
        // with the specified name
        Class c2 = int.class;
        Class c3 = void.class;

        System.out.print("Class represented by c2: ");

        // toString method on c2
        System.out.println(c2.toString());

        System.out.print("Class represented by c3: ");

        // toString method on c3
        System.out.println(c3.toString());
    }
}

Output:

Class represented by c2: int
Class represented by c3: void
